Biopolyester-Based Systems Containing Naturally Occurring Compounds with Enhanced Thermo-Oxidative Stability

Microsoft Word - Thermo-Oxidative Stability

The materials used in this study include HDPE (HD100 from M. Holland Company), PP (Polypropylene 3281 from Total Petrochemicals USA, Inc.) and HIPS (IS200 from M. Holland Company). Each polymer was then compounded with SureFlo at two different levels, 5 and 10%. A Q-500 thermogravemetric analyzer (TGA) was used for the study. In each experiment, the sample (typical size ~ 10 mg) was heated from...

Stability of a Naturally Occurring Virus Inhibitor

We recently described a virus inhibitor (contact-blocking virus inhibitor) which was produced spontaneously by untransformed human and murine cells in tissue culture (S. Baron and L. McKerlie, Infect. Immun. 32:449-453, 1981). This contact-blocking virus inhibitor was characterized by broad antiviral activity, high potency, and reversible inhibition of viral attachment. Unlike interferon, the a...

Naturally Occurring Compounds: New Potential Weapons against Oxidative Stress in Chronic Kidney Disease

Oxidative stress is a well-described imbalance between the production of reactive oxygen species (ROS) and the antioxidant defense system of cells and tissues. The overproduction of free radicals damages all components of the cell (proteins, lipids, nucleic acids) and modifies their physiological functions. As widely described, this condition is a biochemical hallmark of chronic kidney disease ...

Naturally Occurring Compounds for Control of Harmful Snails

Ten naturally occurring compounds have been tested for molluscicidal activity against the fresh water snail, Biomphalaria alexandrina and the white garden snail, Theba pisana. The role of the synergist, piperonyl butoxide (PB) in improving the efficacy of these chemicals was also investigated. The results showed that thymol was the most effective against B. alexandrina snails, followed by trans...
